The board of the Internet Corporation for Assigned Names and Numbers (ICANN) voted 11-1, with three abstentions, to adopt ISOC's proposal for control of the registry.
ISOC set up PIR to act as the .org registry operator. It will subcontract back-end registry services to Afilias of Dublin, the registry operator for the .info domain, ISOC said in a statement.
PIR plans to set up a .org advisory council made up of leaders from non-commercial organisations.
Existing .org users will not notice the transition, ISOC said. They will renew their names through their registrars at the usual time and in the usual way.
ISOC submitted its bid to ICANN on 18 June, as did 10 other organisations. Three teams evaluated these bids, two looking at technical issues and one at the particular needs of the .org domain.
Under a deal between ICANN, Verisign and the US Department of Commerce, Verisign will keep its .com registrar business and will give $5m to PIR to help with operating costs.
